TESTING

DRE’s custom designed field and in-house testing capabilities provide technically accurate demonstrative verification to supplement analyses and research. Our test resources are used to evaluate existing or alternative component and system designs and are supported by data acquisition/signal conditioning equipment capable of on-board (impact and non-impact), off-board, or telemetry acquisition. Testing can be thoroughly documented by high speed, real time and miniature video cameras. Our custom six degrees of freedom watercraft and road vehicle handling instrumentation includes GPS positioning and operator control inputs, and is designed to assess handling and maneuverability in response to driver inputs.

We have performed quasi-static, dynamic and impact tests to measure forces, motion, accelerations, strain, pressure and temperature. Specialized shock table and impulse response testing has been conducted to measure and perform vibration modal analysis, as well as transmissibility and impedance transfer function modeling. Acoustic monitoring has also been performed for various noise assessment applications.

Instrumented anthropomorphic test devices (ATDs) are often used for assessing injury potential and/or injury mitigating device effectiveness. Commonly injured body regions investigated include lumbar spine injuries, cervical spine injuries, and head injuries for adults and children.

Sample marine applications include watercraft handling and maneuverability, staged watercraft crash testing, pressure testing in vessels, pipes and free jet flow, lower explosive limit (LeL) level and Carbon Monoxide (CO) monitoring, slip and fall coefficient of friction testing, propulsion system torque, thrust, and vibration testing, and wave profile and period monitoring.

Sample automotive applications include full scale vehicle impact drop testing and submersions, component level shock table testing, inflatable restraint deployments including out-of-position occupant injury potential evaluations, seat belt pretensioner deployments, seat belt retractor performance evaluations in linear and angular acceleration environments, and quasi-static component ultimate strength testing and force versus deflection characterization.
